3 kg of lead shot was poured into a bucket filled to the top with water. how much has the weight of the bucket and its contents changed?
Vd = Md / Pd = 3kg / 11340kg / m3 = 0.2646 * 10 ^ -3 – volume of shot
Pd = 11340kg / m3 – lead density
Vw = Vd = 0.2646 * 10 ^ -3 m3 – volume of displaced water according to Archimedes’ law
Mw = Vw * Pw = (0.2646 * 10 ^ -3) * 999.23 = 0.264 kg – mass of displaced water
Pw = 999.23kg / m3 – water density
Gd = Md * g = 3 * 9.81 = 29.43 N – the weight of the fraction poured into the bucket
Gw = Mw * g = 0.264 * 9.81 = 2.59 N – weight of water displaced from the bucket
Gd-Gw = 29.43-2.59 = 26.84 N
Answer: the bucket weight will increase by 26.84 N after filling the shot
